Astrocytes play a crucial role in regulating appetite, challenging the belief that neurons are solely responsible for signaling fullness.
Sleep loss has become a quiet constant of modern life. It shows up in early commutes, late-night screens, rotating shifts, and a work culture that treats being reachable as a virtue. The public usually talks about the obvious costs, like fatigue and brain fog. The more consequential costs may be metabolic. When sleep is cut short, appetite often becomes harder to manage. People report stronger cravings, less satisfaction after meals, and a tendency to snack late.
Because GLP-1s reduce the reward value of fatty, sugary and salty food, as well as reduce appetite, many patients go off these foods, said Alexander Miras, a professor of endocrinology at Ulster University. The effect is similar to that in patients who have bariatric surgery, which helps them to lose weight. After bariatric surgery, there is at least a fivefold increase in endogenous GLP-1s that naturally occur in our guts.
